Lourdes Leon has been having a splendid vacation in Cannes, France with her family this summer, and it seems like the daughter of Madonna is basically a full grown adult!

Which is crazy to think about because like seriously - when did this happen?! We remember when she was just a cute little girl!

Lourdes was recently spotted this past Friday swimming in the Atlantic Ocean where she took some time to drift in the water after doing some rough-housing with her brother Rocco and her momma's boyfriend Timor.

We absolutely LOVE the necklace we spotted her wearing that bore her name on it — that along with her bikini top absolutely proves how stylish this lil' lady is!
